    diameters up to 30", sweet.... the belt wouldn't even fit around it. Cool idea though, a single wheel that holds a 72" belt. Set it up like an old medieval grindstone. What would it be... calc tells me just under 23"

    Okay I never new this but there are contact wheels just for the J-cloth belts that help when polishing small radiuses and curves. There are also hard rubber contact wheels that are only grooved in the center, 1/4" on the sides is solid to help extend the belt life when working on the edge of the belt.

    the 20-30" contact wheel that takes bulk sand paper strips is pretty impressive and I can imagine the torque when starting that up:eek:

    Question for guys using cork belts, what polishing compound do you use?

    I found one supplier who said green polish for both cork belts I have one with no grit listed and one with 600 grit listed. However the scratches would not go away no matter what I did now mind you the green polish I was using would not touch 2000 grit sanding lines so it may have been part of the problem I was experiencing.
    Princess Auto polishing compound well you guessed it pretty much junk. Tried some from another supplier and it cut twice as fast however still some lines with the 600 grit cork belt.

    Figured what the heck I was getting no where and changed from green to pink on the cork belt with no grit which really cut down on the lines but still not perfect.
    Now I am assuming that the belt with no grit listed is the finer polishing belt of the two I have and could be wrong, very little difference between the two in reality but they are old used stuff I picked up.

    Someone asked for a Christmas present so waiting on new cork belts is not going to happen.

    Hey John, my cork belt is rated at 800 grit if i remember correctly. I also used the green compound from princess auto, and wasnt happy with it. I had a different green before and it was way better but i dont recall where it came from, so i am still fighting it out with the current green junk until i find some better stuff. Changing compounds on the belt will help some, but going to a finer compound wont be perfect as the belt will still be contaminated with courser grit. If the belts came from another maker, its hard to say what was used on them before also. Most belts are black, so its possible that the previous guy used brown or black that is a lot courser, and could still have some embedded particles. I use my 800 with green for what i would call more of a satin polish. Its shiny, but not a real true mirror. I used to mirror everything, but at this point, i find that a mirror is too hard to maintain, and the time it takes to do the extra hand sanding for a mirror isnt worth it when that time could be spent on other projects or handle finishing.

    You know how fast a mirror polish gets messed oh about the time it takes to use the wrong side of a sponge/scrubby pad on the wrong side .

    Tried the white compound today on a stainless knife and it went much better and will use green on the finer belt. Sometimes it pays to not use old junk, I will be scrapping off all remnants of compound and see how it goes.
    From now on I think I am going with a satin finish primarily and polish only if asked for.

    The green compound I am using right now is a small tube from Lee Valley

    but the stuff from Knifemaker.ca is cheaper
